An image processing device includes: a storage part configured to store a correlation between a pre-deformation color and a post-deformation color that reflects a color variation accompanying a deformation of a medium, with respect to a degree of deformation of the medium; an acquisition part configured to acquire degree-of-deformation information and color information for each region of a deformed object; and a determination part configured to determine a color of the image based on the degree-of-deformation information, the color information, and the correlation, so that the post-deformation color of each region of the deformed object approximates the color information.

2. The image processing device according to claim 1 , wherein the correlation is created in advance by deforming a color sample including a plurality of colors with different area variation ratios and measuring the colors after a shape of the color sample is deformed, such that each color value of the colors of the color sample is designated as the pre-deformation color information, a post-deformation measured color value of the colors of the color sample is designated as the post-deformation color information, and each of the area variation ratios is designated as the degree-of-deformation information.
3. The image processing device according to claim 1 , wherein the correlation is created in advance for each type of the medium.
4. The image processing device according to claim 1 , further comprising a position information input part configured to form a grid having a plurality polygons as elements in advance on the medium before the shape of the medium is deformed, and to input position information of each grid point of the grid before and after the shape of the medium is deformed, the acquisition part being configured to acquire a color of each of the elements as the color designation information for each region of the deformable object and to acquire the area variation ratio of each of the elements as the degree-of-deformation information for each region of the deformable object, the determination part being configured to determine the color of each of the elements based on the correlation and the area variation ratios of the element.
5. The image processing device according to claim 1 , wherein the correlation includes a color value determined by a combination of primary colors in a generic color standard, and the color value is specified as a color of the image that is formed on the pre-deformed portion of the deformable object.
6. The image processing device according to claim 1 , wherein the correlation includes a color value determined by a combination of colorants used for forming the image on the medium, and the color value is specified as a color of the image that is formed on the pre-deformed portion of the deformable object.
7. The image processing device according to claim 1 , wherein the correlation includes a color value determined by a color space of displayable hues, and the color value is specified as the color of the image on the post-deformed portion of the deformable object.
8. The image processing device according to claim 1 , wherein the correlation is a relationship created as a lookup table.
9. An image processing method for a deformable object obtained by deforming a shape of a medium on which an image is formed, the image processing method comprising: acquiring, by an acquisition part, a degree-of-deformation information on a post-deformed portion and a color designation information, the degree-of-deformation information including a degree of deformation with respect to a deformation of the shape of the medium, the post-deformed portion being a predetermined portion of the deformable object, the color designation information designating a color of the image on the post-deformed portion; and determining, by a determination part, a color of the image that is formed on a pre-deformed portion based on the degree-of-deformation information on the post-deformed portion and the color designation information on the post-deformed portion, and a correlation such that a color of the image approximates the color designation information, the pre-deformed portion corresponding to the predetermined portion of the deformable object before the shape of the medium is deformed, the correlation including a pre-deformation color information, the degree-of-deformation information, a post-deformation color information, the pre-deformation color information including a color information on the image that is formed on the pre-deformed portion, the post-deformation color information including a color information of the image on the post-deformed portion, which reflects a color variation caused by deforming the medium by the degree of deformation.
10. The image processing method according to claim 9 , further comprising: creating, by a correlation creation part, the correlation by deforming a color sample with different area variation ratios, measuring colors of the color sample after a shape of the color sample is deformed, and correlating each color value of the colors of the color sample before the shape of the color sample is deformed as the pre-deformation color information and each color value of the colors of the color sample after the shape of the color sample is deformed as the post-deformation color information, and with respect to each of the area variation ratios is designated as the degree-of-deformation information.
11. A non-transitory computer usable medium storing a computer program for causing is a relationship in which one or more computers to execute steps of the image processing method according to claim 9 .
12. A printing system comprising: a personal computer provided with a memory unit including the non-transitory computer usable medium according to claim 11 ; and a printer configured to print the image based on printing data outputted from the personal computer.
